July 6, 2012: AHRI Publishes Standards Establishing Rating Method for CO2 Compressors
ARLINGTON, Va. — The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) announced the publication of standards 570 (I-P)-2012 and 571 (SI)-2012, Performance Rating of Positive Displacement Carbon Dioxide Refrigerant Compressors and Compressor Units, which AHRI stated provides for the first time a rating method for compressors and compressor units that use CO2 as a refrigerant.
“The publication of these standards is the result of nearly six years of effort on the part of AHRI and our members,” said Stephen Yurek, AHRI’s president and CEO. “Prior to publication, there was no available method to rate compressors that use CO2 as a refrigerant.”
